the gradual divergence of species from the population due to genetic polymorphism

Breeding for tolerance to very low or high temperatures

this often specialises in plants that are in demand and can be container grown to save space

he first use the term heterosis in hybrid vigor

Elimination of toxic substances is one of the breeding goals for improving cultivar quality. what is the toxic substance being eliminated from cabbage:

The following are the main undesirable effects of plant breeding on crop improvement except;

the change in the genetic composition of a population

the ancestor of rice from wild perennial is

Is is the place where plants are taken care of before they are finally sold or planted in the field

a form of change in Chromosome number wherein the change was only observed in part of the Chromosome set

the evolution of monocoque plants from dicot plants

Breeding for drawfness is good for some crops because:

the Chromosome number of N. tabacum is.

A discipline that is useful to plant breeding when comparing the performance of many strains.

the success in plant breeding relies on the available

the independent evolution of analogous structure in unrelated species

Resistance to drought, soil salinity, extreme temperatures, heat, wind, cold, and frost.

which is not an advantage of plant nursery management?

the evolution of wheat was done through

the following are principles in darwins theory of evolution through natural selection except

evolution is a population phenomenon, wherein genetic structure evolves not the population

the source of genes for disease resistance and higg tillering traits in sugarcane cultivars

it is the number of individuals with a given genotype divided by the total number of individuals in the population.

a theory of species formation in response to the formation or geographical barries

pollinated date palm as early as 700 B.C.

First to discover the gametophytic system of self-incompatibility in corm

discovered that light stimulus is found at the tip of the plant

proved the existence of a growth substance in oat seedlings and developed the avena test

the Chromosome number of muscles accuminata

there is isolation of individuals in the periphery or border

he laid the fundamental laws of genetics by working on garden peas

this technology revolutionized the propagation and mass production of several species especially for ornamentals

it is the exchange of genetic material between different organisms which leads to production of offspring with combinations of trait that differ from those found in either parents.

these are naturally occurring chemicals produced in one part of the plant and translocation to another part, where they perform physiological functions

First proposed the dominance hypothesis of heterosis

the following crops are example of alloploidy in which more than two sets of chromosomes are homologous except

the Chromosome number of breed wheat

the type of evolution where there is increase in structural complexity and specialisation

it is the place where plants are taken cared before they are finally sold or planted in the field.

plant breeding is?

elimination of toxic substances is one of the breeding goals for improving cultivars quality. what is the toxic substance being eliminated from the seed of cotton:

average yield of many crops have increased over time except for;

it is the only element of evolution that can create new games or alleles

the Philippine Rice Research Institute has a Genetic Resources Division that collects and conserves rice genetic resources to ensure the future generations of available seeds needed to build better rice plants in facing climate change and growing population. in other word, philrice has?

a discipline that is useful to plant breeders in addressing farmers need or preference

the following are alloploid crops having non-homologous set of Chromosome except

the evolution of N. tabacum was done through

A discipline that is useful to plant breeders in utilization which determines market demand for a particular variety

the Chromosome number of emmer wheat is

plant breeder produced a new variety of crops for better plant growth habits that exhibit the following except;

It is the process of multiplying the number of species, perpetuating a species or maintaining the youthfulness of a plant.

developed the concept of progeny test on individual plants selection on cerials

the type of evolution arising from one species

plant breeding is directed and accelerated evolution

familiarization with crop evolution of different species is a prerequisite for plant breeding

plant nurseries are advantageous because

the ancestor of flowering plants

A discipline that is useful for understanding breeding for insect resistance

a type of evolution where two or more species from a similar evolutionary history continue to evolve similar characteristics

the reproductive hormone of plants

developed the world's first transgenic cotton plant in USA

which banana variety is an autotriploid

also known as a wound hormone

it acts as sieve on genetic recombination

a form of change in Chromosome number wherein the change was only observed in the whole set of Chromosomes

several heading varieties of lettuce was developed in?

it is the process of bringing a wild species under human management

he developed the concept of pureline

the direct annual ancestors/progenitor of Zea mays ssp mays

it is the exchange of segments between homologous chromosomes and powerful mechanism for bringing about variation

the following crops exhibit autopolyploidy except
